The linear alkyl chain length effect on the assembly of non‐planar perylene bisimides (PBIs, 1 with ‐C 6 H 13 ; 2 with ‐C 12 H 25 ) has been investigated. It was suggested that π–π stacking predominated in assemblies of 1 with short alkyl chains, while both π–π stacking and van der Waals interactions contributed to the hierarchical assembly of 2 with longer alkyl chains. Thus, by changing the linear chain length, the hierarchical assembly of PBIs modified on bay positions could be manipulated effectively.
